Reaction Steps
1-(4-fluorobenzyl)-5-methanesulfonyl-2-nicotinoylindole (0.14 g), hydrazine monohydrate (0.17 g), potassium hydroxide (0.05 g) and ethylene glycol (3 ml) were added under nitrogen atmosphere and the mixture was stirred at 110° C. for 8 hours. To the reaction solution was added water; and the mixture was extracted with dichloromethane, washed with a saturated aqueous NaCl solution, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The resulting residue was subjected to siilica gel column chromatography (hexane:ethyl acetate=1:3) to obtain 13 mg of the desired product.
